The mortalities caused by the insecticides and mineral oil were significantly different. Diazinon and Malathion with 100% mortality showed the highest toxicity to the different stages of the ladybird. Chlorpyrifos and mineral oil caused less than 30% mortality, while mineral oil had the lowest harmful effect on this predator. Based on LC50 and LC90 values 24h after treatment, the male and female adults of C. montrouzieri were more susceptible to Diazinon (701 and 635; 1257 and 1194ppm) than to Chlorpyrifos (4238 and 4316, 5683 and 5480 ppm). Based on International Organization of Biological Control (IOBC) classification, Chlorpyrifos and mineral oil were classified as category 1 (harmless) and Diazinon and Malathion were placed in category 4 (harmful).}, Keywords = {Acute toxicity,bioassay,Cryptolaemus montrouzieri,organophosphate insecticide,mineral oil}, volume = {7}, Number = {1}, pages = {1-11}, publisher = {Tarbiat Modares University}, url = {http://jcp.modares.ac.ir/article-3-143-en.html}, eprint = {http://jcp.modares.ac.ir/article-3-143-en.pdf}, journal = {Journal of Crop Protection}, issn = {2251-9041}, eissn = {2251-905X}, year = {2018} } @article{ author = {Mohammadpour, Iran and AskariSiahooei, Majeed and Tajeddin, Behjat and Koohpayma, Fatemeh and Bagheri, Abdoolnabi}, title = {Date package and storage conditions play a key role in controlling Plodia interpunctella and Oryzaephilus surinamensis and preserving date quality}, abstract ={Piarom is considered as one of the most important semi-dried date fruits in Iran which has been highly affected by stored pests. The current study was aimed to evaluate the effects of the modified atmosphere packaging (MAP) and vacuum packaging (VAP) methods on storage pests control and date quality. To do so, Piarom variety were packaged in two package systems, including passive modified atmosphere and vacuum package system. The control samples were kept unpackaged. The packages were kept under two different storage conditions; at 4 °C and 55 ± 10% RH, and 25-27 °C and 70 ± 5% RH for 30, 60, 90 and 150 days. The experiment was carried out based on a completely randomized design arranged in factorial with four replicates. The results showed that Indian meal moth Plodia interpunctella (Hübner)and sawtoothed grain beetle Oryzaephilus surinamensis (L.) are the most important storage pests with 87.5 and 12.5% contamination, respectively. The passive MAP and VAP reduced the pests infestation rate significantly compared to control. Also, they could better preserve pH (5.88 and 5.85 for MAP and VAP, respectively) than the control (5.78). Changes in water activity in MAP and VAP were almost the same at the two storage conditions i.e., ambient and at 4 °C and was significantly different from the control.

In this study, we have evaluated the lethal effects and persistence of Zingiber officinale (Roscoe) pure (PEO) and nano-formulated essential oil (NFO) on different developmental stages (egg, male and female adults) of PTM. Essential oil was extracted by hydro-distillation using a Clevenger-type apparatus. The essential oil was analyzed by gas chromatography/mass spectrometry (GC/MS). Nanofibers were produced by electrospinning technique. The morphology of nanofibers was investigated by SEM. Fourier transform infrared (FTIR) was used to identify the characteristic functional groups in the PEO, nanofiber and PEO/NFO scaffold. Bioassays were performed in 250 ml glass jars. The essential oil consisted of α-Zingiberene as the most abundant component (14.21%), followed by Ar-curcumene (12.58%), β-sesquiphellandrene (12.48%) and cis-α-bisabolene (10.29%). The results of FTIR spectra showed the establishment of the functional groups of PEO on the structure of the nanofiber. The images of SEM also demonstrated the establishment of PEO in the structure of the nanofiber. LC50 values of PEO and NFO were estimated 75.44 and 30.24µl/l air for eggs, 19.08 and 10.28µl/l air for female adults, and 17.76 and 9.56µl/l air for male adults, respectively.

The aim of this study was to investigate different biological control agent consortia against Rhizoctonia solani root rot disease of common bean. Bacillus pumilus INR7, Trichoderma harzianum and Rhizophagus intraradices were used individually or in combination. There were two application methods: simultaneous application of biocontrol agents with the plant pathogen, and pre-inoculation of biocontrol agents one month before the pathogen. Treatments containing B.pumilus INR7 were the best treatments for suppression of the disease in the simultaneous application method, where B. pumilus INR7 + T. harzianumreduced the disease up to 54%. However, in pre-inoculation method T. harzianum alone was the only treatment that reduced disease severity up to 49% compared to the infected control; other treatments did not haveany significant effect on disease severity. In current study, combination of T. harzianum and R. intraradices was unable to decrease disease severity and improve plant growth. This phenomenon was common in both simultaneous and pre-inoculation experiments. However, results showed that B. pumilus INR7 and R. intraradices were compatible with each other. Their combination not only decreased the disease, but also improved the dry weight of common bean in both application methods. Our results revealed that B. pumilus INR7 had positive interaction with T. harzianum. This combination increased their ability to suppress root rot disease and improve plant health, significantly.

Identification and assessment of genetic variation in pathogen populations are very important to understanding taxonomy, epidemiology, and management of a pathogen.

A total of 33 pectolytic bacterial strains were isolated on nutrient agar and eosin methylene blue culture media. The isolated strains and five standard strains belonging to P. atrosepticum, P. carotovorum and Dickeya dianthicola were studied. The strains were identified as P. carotovorum subsp. carotovorum on the basis of phenotypic characteristics including: gram-negative, facultative anaerobic, soft rot production on potato slices, growth at 37 °C, and inability to produce acid from α-methyl-D-glucoside and also molecular identification using species-specific primers. Based on Y1/Y2 and ExpccF/ExpccR primers, the expected amplicons (434 and 550 bp fragments, respectively) were obtained for all strains and the standard strains belonging to P. carotovorum.
